N. Korea's military again threatens merciless retaliation for S. Korea, U.S.

SEOUL, March 13 (Yonhap) -- North Korea on Wednesday threatened to unleash merciless retaliation over the ongoing South Korea-U.S. joint military exercises and the United Nations sanctions for its nuclear test.

In a statement released by the Ministry of the People's Armed Forces, the North said that with the armistice agreement and South-North Korea non-aggression pact no longer valid, all that remains is for Pyongyang to retaliate against aggressors.
